ותלבש אסתר מלכות- And Esther wore the clothes of royalty. (Esther, 5:1)
The Pri Tzadik says that it was after having prayed and fasted that Esther Hamalka became dressed in Ruach Hakodesh. She was dressed in strength. She owned her own royalty and without fear at all from Achashveirosh and with certainty of bending his heart to her will. He continues on to say that the Ruach Hakodesh is the attribute of Malchus (royalty). The concept of “Torah Shebial Peh ” is from the attribute of Malchus.
He asks what it was that Esther saw to transform and dress in clothes of royalty, adorning her strength, to rely on a miracle without fear?
He says she looked in the Torah and realized she was the daughter of Sarah Imainu. When she understood that although Sarah lived 127 years which must have included transformation as a child of Terach, she is till was considered by Chazal as being a wholesome and righteous individual. Hashem considered all of her years as one who pursued good. This idea gave Esther the clarity of who she could be by connecting to Sarah Imainu. Once she held on to that she was able to then wear her clothes of royalty. She understood that Hashem would not have given her such an invitation for nothing and she had no doubt that she would be an instrument to save Klal Yisroel.
The Pri Tzadik then goes on to say that each and every person of Yisroel is able to get help from the service of our Avos and Imahos when we are coming to purify ourselves. He says therefore of course each person of Yisroel has the capacity to find a place even in the exalted words of Torah to hope for when one’s actions can reach the level of the actions of our Avos.
It seems that part of the “help” described with the words of בא לטהר מסייעין אותו by Chazal according to the Pri Hatzadik is the ability to connect to the Avodas Hashem of our Avos and Imahos.
What is fascinating to me, is the fact that the shift in her all began with a prayer. This prayer allowed for her to connect to her own Malchus when she was able to identify herself as the daughter of Sarah Imainu. She became a perfect vessel to save all of Klal Yisroel.
“May all our prayers reach such heights and earn such help of Hashem to bring a world redeemed, a world of Moshiach. “
